title: Breakage of shunt devices (Sophy programmable pressure valve) following implantation in the hypochondriac region.
abstract: We report on three cases in which shunt devices (Sophy programmable pressure valve) broke while implanted in the hypochondriac region. None of these patients had an apparent history of trauma related to the shunt valve. The outlet connector was broken at the same site in each case. The dissociation between the movement of the thorax and that of the abdomen may have caused the formation of a crack in the outlet connector.
